A) 574

B) 649

C) 675

D) 593

E) 618

Answer:

Option C

Explanation:

Total production of B from 2006 to 2011

= $ \left(750\times\frac{4}{5}\right)+\left(800\times\frac{7}{8}\right) $

+$\left(600\times\frac{4}{3}\right) +\left(550\times\frac{12}{11}\right)$

+$\left(700\times\frac{13}{14}\right)+\left(650\times\frac{14}{13}\right) $

= (600 + 700 + 800 + 600 + 650 + 700) tonnes = 4050 tonnes.

.'. Average production = $\frac{4050}{6}$ tonnes = 600 tonnes.
